"Rather be a pussy than dead."

Back in my youth/before a few major crashes I'd have been that same punk with the sharp tongue

Whenever something like that happens to me I force myself to just ignore it and keep moving.  Most times it turns out it was just the voices in my head.

I wear a full Aerostich two pieces and I've had "michelin man" comments, I just laugh.  I'm not wearing the gear for them...

"Only pussies hide after calling someone a pussy".

My response would have been "Really?  That's good to know.  Thanks for pointing that out."  He would have been confused for days.

Never lower yourself to the level of the people around you. Meaning, by even uttering a response, you've given him credibility, which he doesn't have, and when arguing with fools, no one can tell the difference. Walk away.
